• SharpPcap - A Packet Capture retring seding messesge problem.

  I trying to capture packets using SharpPcap library. I'm able to return the packets details but I'm having problem to get what the message content inside the packet. the packet using .Data to return the message and when I use it it is returning (System.Byte[]). here is the library website: http://www.codeproject.com/KB/IP/sharppcap.aspx here is my code: string packetData; private void packetCapturingThreadMethod() { Packet packet = null; int countOfPacketCaptures = 0; while ((packet = device.GetNextPacket()) != null) { packet = device.GetNextPacket(); if (packet is TCPPacket) { TCPPacket tcp = (TCPPacket)packet; myPacket tempPacket = new myPacket(); tempPacket.packetType = "TCP"; tempPacket.sourceAddress = Convert.ToString(tcp.SourceAddress); tempPacket.destinationAddress = Convert.ToString(tcp.DestinationAddress); tempPacket.sourcePort = Convert.ToString(tcp.SourcePort); tempPacket.destinationPort = Convert.ToString(tcp.DestinationPort); tempPacket.packetMessage = Convert.ToString(tcp.Data); packetsList.Add(tempPacket); packetData = "Type= TCP" + " Source Address = "+ Convert.ToString(tcp.SourceAddress)+ " Destination Address =" +Convert.ToString(tcp.DestinationAddress)+ " SourcePort =" + Convert.ToString(tcp.SourcePort)+ " SourcePort =" +Convert.ToString(tcp.DestinationPort)+ " Messeage =" + Convert.ToString(tcp.Data); txtpackets.Invoke(new UpdatetxtpacketsCallback(this.Updatetxtpackets), new object[] { packetData }); string[] row = { packetsList[countOfPacketCaptures].packetType, packetsList[countOfPacketCaptures].sourceAddress, packetsList[countOfPacketCaptures].destinationAddress, packetsList[countOfPacketCaptures].sourcePort, packetsList[countOfPacketCaptures].destinationPort, packetsList[countOfPacketCaptures].packetMessage }; try { //dgwPacketInfo.Rows.Add(row); countOfPacketCaptures++; //lblCapturesLabels.Text = Convert.ToString(countOfPacketCaptures); } catch (Exception e) { } } else if (packet is UDPPacket) { UDPPacket udp = (UDPPacket)packet; myPacket tempPacket = new myPacket(); tempPacket.packetType = "UDP"; tempPacket.sourceAddress = Convert.ToString(udp.SourceAddress); tempPacket.destinationAddress = Convert.ToString(udp.DestinationAddress); tempPacket.sourcePort = Convert.ToString(udp.SourcePort); tempPacket.destinationPort = Convert.ToString(udp.DestinationPort); tempPacket.packetMessage = udp.Data.ToArray() + "\n"; packetsList.Add(tempPacket); packetData = "Type= UDP" + " Source Address = "+ Convert.ToString(udp.SourceAddress)+ " Destination Address =" +Convert.ToString(udp.DestinationAddress)+ " SourcePort =" + Convert.ToString(udp.SourcePort)+ " SourcePort =" +Convert.ToString(udp.DestinationPort)+ " Messeage =" + udp.Data.ToArray() + "\n"; string[] row = { packetsList[countOfPacketCaptures].packetType, packetsList[countOfPacketCaptures].sourceAddress, packetsList[countOfPacketCaptures].destinationAddress, packetsList[countOfPacketCaptures].sourcePort, packetsList[countOfPacketCaptures].destinationPort, packetsList[countOfPacketCaptures].packetMessage }; try { //dgwPacketInfo.Rows.Add(row); //countOfPacketCaptures++; //lblCapturesLabels.Text = Convert.ToString(countOfPacketCaptures); txtpackets.Invoke(new UpdatetxtpacketsCallback(this.Updatetxtpackets), new object[] { packetData }); } catch (Exception e) { } } } }

• Filter rows on the basis of "First Name" + "Last Name" in SQL

  - by Raghav Khunger

  Hi, I have a user table in my database which contains two columns FirstName and LastName. Now in my front end there is a textbox to filter out the users from this table. Let's suppose I am taking that input from the front end in the form of a input parameter "@SEARCHKEYWORD". I have created a sample below: DECLARE @Test TABLE ([ID] INT IDENTITY, [FNAME] NVARCHAR(100), [LNAME] NVARCHAR(100) ) INSERT INTO @Test( FNAME, LNAME ) SELECT 'John','Resig' UNION ALL SELECT 'Dave','Ward' UNION ALL SELECT 'Peter','Smith' UNION ALL SELECT 'Dave','Smith' UNION ALL SELECT 'Girija','Acharya' UNION ALL SELECT 'Devendra', 'Gujel' UNION ALL SELECT 'Arjit', 'Gupta' DECLARE @SEARCHKEYWORD NVARCHAR(100) SELECT * FROM @Test WHERE FNAME +' '+ LNAME LIKE @SEARCHKEYWORD i.e. so far I have thought of this query to filter out the rows but it is not giving the desired results: SELECT * FROM @Test WHERE FNAME +' '+ LNAME LIKE @SEARCHKEYWORD Here are the desired outputs which I needed for the inputs mentioned below: --WHEN @SEARCHKEYWORD='John Resig' --Desired OUTPUT: the row which contains 'John','Resig' --WHEN @SEARCHKEYWORD='Ac' --Desired OUTPUT: the row which contains 'Girija','Acharya' --WHEN @SEARCHKEYWORD='Smith' --Desired OUTPUT: the row which contains 'Peter','Smith' and 'Dave','Smith' --WHEN @SEARCHKEYWORD='g' --Desired OUTPUT: the row which contains 'Devendra', 'Gujel' and 'Arjit', 'Gupta' --WHEN @SEARCHKEYWORD='Smith' --Desired OUTPUT: the row which contains 'Peter','Smith' and 'Dave','Smith'

• OpenSSL.NET can't export private key with null Cipher

  - by Nick

  I've recently discovered OpenSSL.NET and it's a pretty sweet little wrapper. I'm trying to execute the following code: public static void DoSomething(byte[] buf) { OpenSSL.Core.BIO input = new OpenSSL.Core.BIO(buf); OpenSSL.X509.X509Certificate b = OpenSSL.X509.X509Certificate.FromPKCS12(input, "passphrase"); OpenSSL.Core.BIO outs = OpenSSL.Core.BIO.MemoryBuffer(false); b.PrivateKey.WritePrivateKey(outs, OpenSSL.Crypto.Cipher.Null, "passphrase"); outs.SetClose(OpenSSL.Core.BIO.CloseOption.Close); Console.WriteLine(outs.ReadString()); } Problem comes at the "b.PrivateKey.WritePrivateKey(.." line. I want to write the private key out without any encryption. According to spec, if I use a Null cipher type this should do the trick, but it never works, regardless of the cert I use in buf. Here's the exception: error:0D0A706C:asn1 encoding routines:PKCS5_pbe2_set:cipher has no object identifier error:2307D00D:PKCS12 routines:PKCS8_encrypt:ASN1 lib I know this part works fine because if I specify any other cipher type, it exports the private key without fail. Anyone have any suggestions?

• gunit syntax for tree walker with a flat list of nodes

  - by Kaleb Pederson

  Here's a simple gunit test for a portion of my tree grammar which generates a flat list of nodes: objectOption walks objectOption: <<one:"value">> -> (one "value") Although you define a tree in ANTLR's rewrite syntax using a caret (i.e. ^(ROOT child...)), gunit matches trees without the caret, so the above represents a tree and it's not surprising that it fails: it's a flat list of nodes and not a tree. This results in a test failure: 1 failures found: test2 (objectOption walks objectOption, line17) - expected: (one \"value\") actual: one \"value\" Another option which seems intuitive is to leave off the parenthesis, like this: objectOption walks objectOption: <<one:"value">> -> one "value" But gunit doesn't like this syntax. It seems to result in a parse failure in the gunit grammar: line 17:20 no viable alternative at input 'one' line 17:24 missing ':' at 'value' line 0:-1 no viable alternative at input '<EOF>' java.lang.NullPointerException at org.antlr.gunit.OutputTest.getExpected(OutputTest.java:65) at org.antlr.gunit.gUnitExecutor.executeTests(gUnitExecutor.java:245) ... What is the correct way to match a flat tree?

• Which platform can we expect one's complement being used there?

  - by Jian Lin

  For some questions such as checking whether a number is odd or even, I noted the comment, a & 1 won't work when it is a one's complement machine or when the code is ported to a platform that uses one's complement. Since 30 years ago on the Superboard, TRS-80, Apple II, I haven't seen a system with one's complement. Are there popular systems that use one's complement still, or do we have some cell phone or mobile device that uses one's complement?

• Flex, Ant, mxmlc and conditional compilation

  - by Rezmason

  My ActionScript project builds with several compile-time specified constants. They are all Booleans, and only one of them is true at any given time. The rest must be false. When I represented my build process in a bash script, I could loop through the names of all these constants, set one of them to be true and the rest to be false, then concatenate them onto a string to be inserted as a set of arguments passed to mxmlc. In Ant, looping is more complicated. I've tried the ant-contrib for tag: <mxmlc file='blah' output='blah'> <!- ... -> <for list='${commaSeparatedListOfConstNames}' param='constName'> <sequential> <define> <name>${constName}</name> <value>${constName} == ${theTrueConst}</value> <!-- (mxmlc's define arguments can be strings that are evaluated at compile time) --> </define> </sequential> </for> </mxmlc> Long story short, ant-contrib tags like the for tag can't go in the mxmlc task. So now I'm using Ant's propertyregex to take my list of arguments and format them into a set of define args, like my old bash script: <propertyregex property='defLine.first' override='false' input='${commaSeparatedListOfConstNames}' regexp='([^\|]+)\,' replace='\1,false ' /> <propertyregex property='defLine.final' input='${defLine.first}' regexp='(@{theTrueConst}\,)false' replace='\1true' /> <!-- result: -define+=CONST_ONE,false -define+=CONST_TWO,false -define+=TRUE_CONST,true --> Now my problem is, what can I do with this mxmlc argument and the mxmlc task? Apparently arg tags can go inside the mxmlc task without it throwing an error, but they don't seem to have any effect. What am I supposed to do? How do I make this work with the mxmlc task?

• ERROR_SEM_TIMEOUT when using WinUSB WritePipe

  - by Ted N

  I often get ERROR_SEM_TIMEOUT errors using the WinUSB WritePipe function. This would seem to indicate that there is a timeout, but if I wait a period of time and try again I'm never able to write. I'm writing in 64 byte chucks to the USB device and often don't have problems. Once I start getting the error, I may have to unplug the usb and and close my app before trying again. Has anybody experienced this problem?

• Using Unicode in fancyvrb’s VerbatimOut

  - by Konrad Rudolph

  Problem VerbatimOut from the “fancyvrb” package doesn’t play nicely with UTF-8 characters. Minimal working example: \documentclass{minimal} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{fancyvrb} \begin{document} \begin{VerbatimOut}{\jobname.test} é \end{VerbatimOut} \input{\jobname.test} \end{document} Error message When compiled using pdflatex mini, this gives the error File ended while scanning use of \UTFviii@three@octets. A different error occurs when the sole occurrence of é above is replaced by something else, e.g. é */: Package inputenc Error: Unicode char \u8:### not set up for use with LaTeX. – indicating that in this case, LaTeX succeeds in reading a multi-byte UTF-8 character, but not knowing what to do with it (i.e. it’s the wrong character). In fact, when I open the produced .test file manually, it contains the character é, but in Latin-1 encoding! Proof: when I open the files in a hex editor, I get the following: Original file: C3 A9 (corresponds to LATIN SMALL LETTER E WITH ACUTE in UTF-8) Written file: E9 (corresponds to é in Latin-1) Question How to set VerbatimOut up correctly? filecontents* (from “filecontents”) shows that it can work. Unfortunately, I don’t understand either code so I cannot fix fancyvrb’s code by replicating the logic from filecontents manually. I also cannot use filecontents* instead of VerbatimOut because the former doesn’t work within a \newenvironment, while the latter does. (Oh, by the way: vanilla Verbatim instead of VerbatimOut also works as expected. The error seems to occur when writing the file, not when reading the verbatim input)

• Using a4j:support 's onchange event with h:selectOneMenu

  - by user339637

  <h:selectOneMenu id="selectOneMenu" value="#{Bean1.val1}" > <f:selectItems value="#{Bean1.selectItems}"/> <a4j:support event="onchange" action="#{Bean1.onSelectOneMenuChange}" reRender="textbox1 , textbox2 , textbox3, textbox4" /> </h:selectOneMenu> <h:inputText id="textbox1" value="#{Bean1.textbox1}"> </h:inputText> <h:inputText id="textbox2" value="#{Bean1.textbox2}"> </h:inputText> <h:inputText id="textbox3" value="#{Bean1.textbox3}"> </h:inputText> <h:inputText id="textbox4" value="#{Bean1.textbox4}"> </h:inputText> Bean1.onSelectOneMenuChange() will change the value of Bean1.textbox1 , Bean1.textbox2,Bean1.textbox3 and Bean1.textbox4 depending on the value selected (Bean1.val1) .Sometimes , it will change all the textbox value and sometimes it will only changes some textbox value. When users change the value in the "selectOneMenu" drop down list control , the JSF framework will not call the update model values phase but call the Bean1.onSelectOneMenuChange() directly. After that , the all the textbox are reRender. Because the update model values phase is not called , the values entered by the user is never set the the Bean1 and the original value is shown in the textbox after reRender . So I want to ask: How can I manually call the update model values phase inside Bean1.onSelectOneMenuChange() ?How can I get the value input input by the users inside Bean1.onSelectOneMenuChange() and set it to the corresponding fields of the Bean1 ? 2.Another approach is that only reRender those textbox whose values are updated inside the Bean1.onSelectOneMenuChange() .However , there are many cases . For example , a value will change all the textbox value and a values may only change some textbox value.How can I reRender conditionally ? What method is more prefer for maintainability?

• Powershell: Select-Object with additional calculated difference value

  - by David.Chu.ca

  Let me explain my question. I have a daily report about one PC's free space as in text file (sp.txt) like: DateTime FreeSpace(MB) ----- ------------- 03/01/2010 100.43 DateTime FreeSpace(MB) ----- ------------- 03/02/2010 98.31 .... Then I need to use this file as input to generate a report with difference of free space between dates: DateTime FreeSpace(MB) Change ----- ------------- ------ 03/01/2010 100.43 03/02/2010 98.31 2.12 .... Here are some codes I have to get above result without the additional "Change" calculation: Get-Content "C:\report\sp.txt" ` | where {$_.trim().length -gt 0 -and -not ($_ -like "Date*") -and -not ($_ -like "---*")} ` | Select-Object @{Name='DateTime'; expression={[DateTime]::Parse($_.SubString(0, 10).Trim())}}, ` @{Name='FreeSpace(MB)'; expression={$_.SubString(12, 12).Trim()}}, ` | Sort-Object DateTime ` | Select-Object DateTime, 'FreeSpace(MB)' |ft -AutoSize # how to add additional column Change to this Select-Object? My understanding is that Select-Object will return a collection of objects. Here I create this collection from an input text file(parse each line into parts: datetime and freespace(MB)). In order to calculate the difference between dates, I guess that I need to add additional calculated value to the result of the last Select-Object, or pipe the result to another Select-Object with the calculation as additional property or column. In order to do it, I need to get the previous row's FreeSpace value. Not sure if it is possible and how?
